In my opinion, check them off your list. There have been many problems with these rifles over the years as far as quality and performance.
To be honest, you can use an all steel barrel and get nearly the same weight as a carbon barrel if you use small diameter all steel barrels.
I just built two barreled receivers for two customers. One was using a 26" carbon fiber barrel, the other was a 27" Lilja #7 contour, similiar to the Rem Sendero contour.
The difference between the two barreled receivers was only around 12 oz and that was using a heavy all steel barrel. Dropping to a #5 contour Lilja all steel barrel would have made the all steel barreled receiver lighter then the carbon fiber barrel.
Now if your looking to get a heavy barreled rifle as light as possible, yes the carbon fiber barrels have their advantages compared to very heavy all steel barrels but compared to light contour all steel barrels, It is my personal opinion that they do not offer much of an advantage and dispite what is claimed, a carbon wrapped barrel is no where near as stiff and rigid as an all steel barrel.
Heat control, yes the new carbon wrapped barrels do this well but that is the only real advantage I see.
That is not to say they do not shoot. I have built several rifles using ABS carbon wrapped barrels and ALL have been extremely fine shooting rifles, I have just not been able to convince myself they are worth the extra cost yet but they are certainly vrey quality barrels.
